How to Acquire Discernment of Thoughts

Evagrius. "On thoughts".

26. How to Acquire the Knowledge of Discernment.

If any of the hermits wishes to receive from the Lord the knowledge of discernment (diakrisis), he should first work eagerly at the commandments that are at hand [in his power], not omitting anything. And so at the time of prayer he should request knowledge from God, who gives generously to all without reproaching; but let him ask without doubting (Jas 1:5), not thrown about by waves of doubt (cf. Mt. 8:24) , and it will be given him (Jas 1:5).

For it is not possible to receive knowledge of even more matters if one has been neglectful of those matters already known otherwise, having transgressed greatly one would be answerable for even more sins.

And it is a blessed thing to serve the knowledge of God, for it is truly dangerous not to do what [such knowledge] advises, and it is blessed to do all that it teaches.

The nous [wanders in] circles when it is impassioned (empathēs) and becomes difficult to restrain when it reflects [within itself] on matters that produce pleasures.

But it ceases to wander when, having attained apatheia, it meets the incorporeal [beings], who fulfill its spiritual desires (epithumias).

HOWEVER, it is impossible to receive knowledge without having made the first, second, and third renunciation[s].

The first renunciation is to voluntarily leave all worldly things for the knowledge of God; the second is the casting aside of evil which occurs through the grace of Christ our Savior and the zeal of the human person; the third renunciation is separation from ignorance concerning those things that are naturally manifested to people in accordance with their state.

Danger of Delusion When Living in Solitude

St. Ignatius (Brianchaninov). "On Prelest". On Hermitic Life.

St. Ignatius (Brianchaninov)

Let it be known to beloved brothers that the highest types of monastic life, such as hermitage in a desert place or silence in the seclusion, as well as living under the guidance of a spiritual elder with complete obedience to him, were arranged not by chance or human discretion and reason, but by a special providence, determination, vocation and revelation of God. Saint Anthony the Great, the father of monasticism, the founder of the hermitic life, retreated to the desert, when he had been already endued with power from on high and in no other way than being called by God. Though it is not said in the Life of St. Anthony, but further events in the life of this Venerable father clearly prove it. And the description of his life (The Life of Venerable Anthony the Great. Menaion Reader for 17 January and Vitae Patrum Patrologiae coursus complectus, vol. LXXUI) says clearly that he was instructed by God’s voice and command to go to the deepest (inner) desert for the strictest silence. The Cherubim appeared to Venerable Macarius the Great, a contemporary of Saint Anthony, who was a little younger than the latter, showed him a fruitless wild plain – afterwards the famous Egyptian Skete – commanded him to have his dwelling there and prophesized that many hermits will dwell the desert valley (Alphabetic Patericon). St. Arsenius the Great, when he was in the royal palace, prayed to God to show him the way of salvation and heard the voice: “Arsenius, flee from men, and you shall be saved”. Arsenius retreated to the mentioned Skete and there prayed to God again to teach him how to be saved and again, he heard the voice: “Arsenius, flee (from men) and dwell in silence, these are the roots of virtue” (Alphabetic Patericon and Apophthegmata Patrum). Venerable Mary of Egypt was called to the hermitic life in the Transjordanian desert by God’s command (Menaion Reader for 1 April). God, who called to the silent and hermitic life those He had chosen, i.e. those that He foresaw to be capable of living the silent and hermitic life, provided them also with such means and aids for such life, which a man cannot find by himself. And in those times, when the monasticism blossomed, when there were many spiritual elders, only few were considered capable of living in silence, especially of living the hermitic life. St. John Climacus says: “Only a few can live in true solitude (silence); in fact, only those who have obtained divine consolation for encouragement in their labours and divine co-operation in their struggles” (Step 4, par. 120). “Solitude (silence) chokes the inexperienced” (Step 27, par. 5). Recluses and hermits often suffered greatest spiritual adversities: those, who retired into seclusion out of their own will, not being called by God, suffered adversities.
